[Q] Slow Charge - T-Mobile Samsung Galaxy S II SGH-T989

Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?

When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.

Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.

you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs

When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.

I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?

Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.

Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.

Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.

Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here

Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.

so this is nothing a kernel or any other tweak can fix?

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.

the 2A chargers from BlackBerry are the best

So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

Shocking Battery Story..

I've just driven over 400 miles...
I was using my Desire with Co Pilot to navigate me from Scotland to Bristol...
The phone was in my phone holder which is placed in the cigarette lighter so the phone can apparently be charged at the same time as being held...
The phone showed that it was "charging" and yet it still ran out of power....
That's right.. the CHARGING phone RAN OUT of power and switched off!!!!!!! TWICE!!!!!!!!
Has anyone else experienced this? I can't imagine that this phone uses more power than the charge being applied?!
I used my Desire as GPS (with Copilot) the phone had 70% - 80% battery and after sometime it actually charged to 100%. Maybe there is some malfunction in your car charger or just not making a good contact in cigarette lighter plug. Check if charger's led lights all the time.
car chargers trickle charge so they prob couldn't keep up with the demands of CoPilot on the phone

You need to ensure that the car charger is rated at 1AMP at 5V otherwise it will as stated only trickle charge. I've heard this story on other devices. Do you have a genuine HTC charger?
Also if the device gets to warm, it will stop charging in order to avoid damage.
Thanks for the reply guys!
No, it's not a geniune one... I tried 2 different ones, both the universal holder/chargers from Mobile Fun..
So far they've both been fantastic until this little phone came along...!
Connections have been fine, which is the strange thing..
It did get hot though, so you may be right Ardsar... Any way of keeping it cooled?

Same as what others say as well. Your car charger doesn't supply enough amps to keep up.
Ofcourse it gets really hot, navigation is one of the most heavy thing you can do on the phone. And while doing that you charge it at the same time in perhaps a warm car as well.
But, get a 1A charger, not a 500mah like most are.
Same goes for hooking it on the computer, the usb port might not give enough power so the phone can drain itself when doing real heavy stuff.
Plugging something in does not guarantee it will work, you have to know what you plug in

Of course you will - USB ports can only supply upto 500mA if you have nothing else connected to the USB HOst.
Same story for me.
I got a 550 mA car charger, and battery wasn't charging but slowly discharging (about 5-10% per hour) with navi+HDSPA.
Thought, well, 550 mA is not enough, let's see the plug charger from Desire box: that's 1000 mA. Let's go get a 1A car charger.
Got this www . p4c.philips. com/cgi-bin/dcbint/cpindex.pl?ctn=DLM2206/10&slg=it&scy=IT (saw off spaces) which is rated 5V-1A.
Plugged in, started navigating+HDSPA for satellite layer, and still wasn't charging but discharging at a rate of about 4% per hour.
I'm really annoyed 'bout this, I spent 20+15€ for both chargers, I do not want to spend another 25€ for OEM charger....it's unbelivable that I'd finish to buy 60€ of chargers to find out one that do not let battery deplete.
As a final test, I'll try a different cable from original HTC sync cable included in the box...let's see.

Can anyone who has used this confirm it will manage to charge fully even while the Desire is running a satnav program?
Why don't you plug in your normal charger and start running a navigation demo or something.
Not sure if that uses as much energy, but I think it most probably will. The original charger outputs 1A.
If the socket charger does the job, but not the car charger (read: you can also run a navigation demo in the car using that charger) your car charger might not be supplying enough energy as it should.
Or you can use a multimeter and see how many amps it outputs. But the pins are a bit smallish
Tried with another cable (not the original sync one) with just power wires connected, same story: I'll try with the original wall plug charger and see if it does the same or not, as both the Philips charger and the original HTC wall charger are rated 5V-1A
It does get very hot. I used my gps for 9 hours in a row and at the end it got too hot or something and the phone just rebooted.
Still It wasn't because the battery had run out of juice it was still good.
Also it was streaming music over bluetooth at the same time.
Used Nav for 1 hour this morning on the way to work while charging from the official HTC car charger. Phone now sat on my desk, battery reporting 100%.
The phone did get pretty hot though...

FYI, not all chargers are equal. I believe that HTC devices need a combination of pins to be connected on the USB port to "tell" the phone that it's connected to a real charger and not a USB port, otherwise the phone will only pull 0.5A, regardless of the output capacity of the charger.
This always used to apply to older HTC phones, and I can't see why they'd change it, so it's quite possible that your 1A Philips charger will not charge the same as my 1A HTC charger...
If in doubt, OEM

That's what I thought, as I imagined that: I hoped that another cable I have, which has USB on one side and a 2 poles connector on the other side on which you connect various connectors, would be recognized by Desire as being a pure power cable. I wasn't lucky.
Since OEM is out for 25€, I tried with non OEM before to save some, but till now I buyed 35€ worth chargers, I'd have to stick with OEM
But now I'm really reluctant on getting OEM, since I do not want to end with spending 60€ in order to have my phone charged while navigating....I'll try to tinker some, and if I'll find out how, I'll report
I had the same problem by using a 1.5A car charger which is working great with iPhone.
As for the PC USB charge... are you sure it can't output 1A to charge the device??

USB2 specs do say that ports shall provide max 500 mA, ehnce motherboards have this limit.
BTW, here's a discussion I've found about the "cable" problem

I'll try to tinker with some cheap cable and see if this works.

TB & Chargers from Other Manufacturer's

So I have the original usb cord and plug hooked up in the bedroom to plug my TB overnight and a blackberry bold charger in the living room because its extra long. Wife and I use the living room one and take turns. Plus I have the original micro usb cable from a Droid X plugged into my PC. At work there is a community charger that we all use by the locker room that has a Motorola brand on it. No one knows who it belongs to or what phone it was made for.
Bedroom and living room chargers seem to charge at an expected rate, even while the phone is in use. Usb on the pc seems to charge faster, and the one at work seems to charge at the slowest pace ever. I left it on the charger for two hours while still using the phone and only got a 10 percent increase. WTF.
Here is the kicker tho. When I had a Droid X, I used the same setup at home and at work and all charged well. Does my TB not like to play with chargers from other manufacturer's?
Side note, near the end of this post I was interrupted by a coworker and had a ten minute conversation while my TB auto locked and sat there plugged in. When I got back to it, it jumped an extra 5 percent.

I'm pretty sure computer USB ports can only output 500mA, the stock HTC wall charger is 1A, your other chargers might be outputting less amperage which is why you're seeing slower charge times. Our TB wants 1A so it chargers pretty slow when using weaker power sources.

^this is right on. Anything less than 1A and you're going to get LONG charge times. I use an old Moto car charger which puts out 850ma and it's not too bad unless GPS and 4G are on, then it barely powers the device and chargers so if you need/want GPS and 4G you'll need a 1A car charger (I'm shopping for one now).
My question is has anyone tried anything above 1A?? There are some new car chargers that put out 2A for tablets which sounds like it could quickly charge the TB but I'm wondering if that's not too much juice.
Don't use anything above what the phone wants it could explode

Charge with USB or the wall charger?

I know that this is a really lame question but I was wondering if one offers a "better" charge? USB charges very slowly compared to the wall charger so I dont want to use it unless I have to.
Also, why does the car charger have a USB hub for the charging cable that comes with the phone if it has a micro USB hub on the end of the cable that is connected to the charger anyways? That is just redundant, is it not?
The wall charger will charge faster... As for 'better'? A charged battery is a charged battery. If you charge it faster than the wall charger allows, there's a potential for overloading the battery (though there should be safeguards to prevent explosive results). But the wall charger is what I'd suggest.
As for the car charger, it's to allow multiple devices. Micro USB for your phone, and a USB port to plug in anything else that might need it (like an iPad or something). If you don't have 2 devices, ignore the USB port and just use the micro USB connection.

Thank you.
Most USB-based charging only goes at 500mA, where as the OEM charger is about 1.5 amps (1500mA). You can find some 2.0A USB car chargers on eBay / Amazon for fairly cheap. They're worth it to get a full charge if you are in a hurry or have a short commute.
Here's one that's 2.1A for $9.99 on Amazon

It makes sense that your phone got hot. When using the stock charger (or any charger with a current rating of 1A or less), the charger is the one that is limiting the current to the battery, so the current-limiting circuit in the phone is not necessarily active and therefore not generating much heat. However, when using the iPad charger (which is rated around 2.5A, I think), the current-limiting circuit in the charger is not active because the 1A or so that the phone is drawing is well within the rating of the charger. Therefore in this case, the current-limiting circuit in the phone needs to actively limit the current and thereby generate a lot of heat.
I personally think that it's better to just use a charger that has a similar current rating to the stock charger. I higher-rated one might charge the battery just fine, but I'd rather keep all of that heat in the charger and away from the battery. Although, of course I could be mistaken -- feel free to correct me if I am wrong.

Battery draining while plugged in to charger

I was watching the Mavericks vs Thunder game using the watch ESPN app and my nexus battery was at about 93%
I watch since halftime to the end of the game and I was plugged in to a car charger the whole time and when the game ended about 1 1/2 hrs later the battery had dropped to 53%. Can't understand it. Hope someone here can explain this to me.
Phone is galaxy nexus, obviously, the battery is the 2100 OEM battery from Verizon store, charger is a belkin dual outlet 1amp micro car charger with the cable that came with a Droid charge.

5V right? that's not a huge draw at all on your battery, i'm assuming your car was either running or started right up afterwards...you can be certain your phone was getting that full 1A especially if your car was running. if your phone showed charging and your phone will normally charge from your car like that then you shouldve been in good shape. despite what you may think, i actually am trying to present relevant info lol but ummm other than that? i would definitely try a multimeter (.....if you have one.....) cuz that would show you exactly what you're getting in/out. usb pinouts should be somewhere on the internet. other than that, try doing the same thing (except for maybe a shorter time period if preferred) on a wall charger which should be more reliable and compare results. i've had devices that burn power faster than they receive them....but the good ole gnex? im not so sure. (engineer here).
I just recently join big red and coming from sprint with an evo 4g and didnt have this issue with that phone and same charger. I'm definitely going to try it with home charger to see if its the charger.
Extra info, the vehicle was powered on before I plugged in the charger, in case it matters any.
Thanks to all the reply thus far.

I find that under heavy usage, only the plug in wall charger gives enough juice to keep it increasing... and even that can go flat or decrease if you are really pushing it... also the way the battery stats are displayed can be flaky too... jumps in the level of charge and quick drops... hard to tell how accurate the reading is.
I hear you. That's crazy, basically the phone draws more power that the charger can provide. I would think the charger should be fine since its 1 amp just like the home charger.

The phone can use more power than a car charger can supply. This is commonly posted all over. Check your car charger, its likely a 0.5 amp. Buy a 1 amp or higher.

Your problem is the charger, 1 amp is the sum of the two outlets, hence you're only giving your phone 500mA max. When charging at that low of a rate, you'll drain the battery when doing anything power intensive on the phone. Your only remedies for this is to get a car charger that's capable of putting out 1 amp or more on a single line. What I personally did was get the Griffin Powerjolt dual charger for $8 on Amazon, opened it up, and soldered the center data pins on each port together.

I though that the griffin powerjolt dual outlet charger would dish out 1amp on a single port if the 2nd port was not being used. Interesting, I can see your point. Would you happen to have a picture of, or remember which are the two that need to be bridge inside to make it a full 1amp output?
Thanks in advance.

Okay, I tried what you said and I got weird results. I used the awkward griffin powerjolt dual outlet car charger. I tried using two different cables, one was from my girl's Droid charge and when I plugged it in and check the status it said usb charging, then I plugged in a cable that came with a i go green adapter that I had purchased at an airport and the phone said ac charging. Unless the cable that came with the Droid charge can only pass 500mamp, I'm puzzle.
Both were plugged in at same time and also both cables were tried by themselves in each outlet of the griffin charger by themselves.
Interesting huh. I will keep testing and see what gives, last resort I get a more powerful car charger. Will keep you guys posted, thanks to everyone that contributed and pitch in thus far.

Got an update on this issue. I streamed another 45 mins to 1 hr of ESPN using watch ESPN app and the results are even more interesting. I was using the wall charger that came with the Droid charge and the USB cable that came with the I go green wall adapter that I have purchased at an airport a while back. Here is what happened, when I started streaming the battery was at 94% and I plugged in phone to charger and under settings/about/status it showed AC charging. After 45 mins to 1 hr of streaming the phone was extremely Hot towards the center of the back and below the cam lenses and led light. Also the battery had dropped to 93% and the phone status showed not charging, even though the battery icon on home screen next to clock shows the lightning symbol inside the battery like is charging.
I don't understand what is happening. Grrrrrr. This is using a wall a charger for a droid charge. Now of to trying it with the OEM charger and cable.

Exactly, in the driver i think the overheat is set to 140F. Also when your charger showed as usb it only gets 509mA and when showing ac it gets the full 1 amp. So just pay attention next time and see if it drains when showing ac.
My car charger is a 1.3 amp and always shows as ac and never drains while charging.

I though about that but then I was wondering, shouldn't the wall charger provide enough power to run everything in there while charging the battery or even without the battery in the phone. Like shouldn't the battery hold the charge that it already has when I started streaming as long as the charger is 1amp?
I would not care if when I stream the phone battery would just hold its charge at what it has at the moment even if it does not charge while streaming. Hopefully that is clear to understand.
To all the fellow galaxy nexus owners out there, maybe you all can test on your phones and see if you get same results as me. Download watch espn and stream the channel for 30 mins, notice what is your battery level before you start streaming, of course plug the phone to a car charger or wall charger and see if battery remains the same, drops charge, or gain charge at the end of 30 mins, or maybe an hour. I am not asking you to watch it for the 30 mins or 1 hour, just let it run and see what happen, if you can of course. only reason why I ask for watch espn is because it is the app that I have been using to stream nba games for the last few days.
Another thing since I am already here with this streaming issue, I have an original SlingBox, the cheapest of the cheapest when they first came out, just coax and that is it. I would like to know if I pay the $29.99 for the app from the market when i switch roms on my galaxy nexus would I lose the app? I have already unlocked and rooted my galaxy nexus and lets say I buy the app and I am running cm9 when I purchase it, if I change to gummy rom or back to a stock rom while still rooted would I have to re-buy the app ?
Thanks in advance for all the input.
Have u tried underclocking cpu with setcpu app?

No I haven't try that. I am currently testing out roms like a mad man trying to find the best for my liking. Question for ya, As far as I know that is kernel dependent right? Like the kernel has to support it, if so which kernels do support it and what would be good underclocking settings ?
I get similar results while using navigation and pandora at the same time, the phone uses more juice than the car charger can provide.
Ironically I plugged in the oem charger and oem cable from the galaxy nexus box and open it (didn't really wanyed to do that) and streamed 30 mins of espn on watch espn and battery was at 70% when I started after 30 mins streaming it had actually climb to 78%. Confused yet everyone? What gives?

Not all that odd. Using my Fascinate charger (0.7 amp) I get noticeably slower charge times than the OEM charger (1 amp). I don't use my phone much while I'm charging so I can't provide any feedback for that.
What is the Droid Charge charger rated at?

Extremely slow charging with micro USB 2.0

This weekend I manged to leave my included Note III Micro USB B 3.0 charger at a friends. I didn't think it was a big deal because I knew I had plenty of micro USB 2.0 Cables I could use in the meantime as they are supposedly backwards compatible.
I was home watching football for most of the day yesterday. The phone charged all day yesterday but I don't remember it ever getting as high as 45%. I didn't get worried until last night when I looked closely and realized the percentage was declining as I used and charged it.
When I went to sleep at about 12:30am I was at 9%. My WiFi and 4Glte were both off and I wok up at 5:30 am to find my phone at 63% only after 5 hours. This is the same charger I used with my Samsung Galaxy S3 just over a week ago til I got this. Why isn't it charging. I'm afraid I'm harming my battery somehow. That's why I'm writing this at 5:45 am instead of sleeping. Any help would be appreciated. Thanks.
P.S. In the 10 minutes it's taken me to write out this thread my battery has declined to 62. (Still on charger)

I had a usb2.0 cable plugged in in my car and I went skiing and streamed music and did the same while plugged in on the way home. I don't know if the cable just slowed battery usage or not but it was plugged in for 2 hours on the way home and I still lost like 5% while plugged in. I bought a USB3.0 cable off Amazon and it works well in my car, not as fast as plugged in to the wall charger but much better than 2.0

I understand that 3.0 will be faster but this is horrendous. It's now 8 hours since I plugged it in and I'm at 74%. And it's plugged in to a wall adapter not a computer or car. Haven't even had this phone for two weeks. Samsung you're killing me here.

Not sure. My phone charges the same on both 2 and 3. I know data transfer is faster on 3. I don't think charging is.

It's not, at least, not from a wall charger that follows the specs. USB3 will charge faster from a computer with the drivers set up properly, but the stock wall plug is 2A (max), all the time. If you get better charging from a USB3 cable, your USB2 cable is probably using really thin wires or just is wearing out.
Some generic chargers are all over the place. Some don't short the data lines so the phone doesn't know if it should be able to fast-charge. Some don't actually put out the current they are rated for.
IF you use the charger the phone came with, and a GOOD USB2/3 cable, it will charge properly. If its not, you have something wrong in your setup. I use the charger that came with the N3 (and the N2), and a Nook or a Monoprice.com USB2 cable. Nice fast charging. I have never used the USB3 cable as I prefer to be able to charge other devices from the same cable and I don't own any USB3 computers.
I also get good charge speed from an older HTC 1A charger. Not as fast, but faster than I expected to get. Note that's a charger that came with a G2 and G2x, not some ebay crap. That's not to say that generic ebay chargers can't be good chargers, just that many of them aren't. If in doubt, use all OEM stuff, at least for testing.
What's probably happening for most people having slow charging on older and/or generic charging setups is one of these...
1) The charger doesn't short the data pins so the phone thinks it's connected to a computer USB and limits charge current to 500mA.
2) The charger doesn't output what the writing on the side claims, and the phone detects this, so it limits itself to charging as best it can.
3) The USB cable uses small, cheap wires and creates too much voltage drop, causing the phone to limit its charge rate.
4) Connector wear is causing voltage drops due to a bad connection. Try a new cable. Not a different cable, a NEW cable.
5) Your Note3 is defective and needs to be replaced. This isn't real likely, but damage to the USB port could cause it.
The Note wants a lot more current than older devices. It also has a system to detect issues that older phones didn't have. I think the first I saw with it was the N2. The phone detects voltage fluctuations under load and adjusts its current draw to keep the voltage as steady as it can. This makes the device more picky about having a good charger and cable. That can be a pain, but it also prevents overloading the charger, which could be something expensive like a computer, which prevents damage. Note that this doesn't harm the battery, it just won't charge as fast as you might like. At 500mA, it's actually possible for the phone to use more than that, so your charge will go down while plugged in. That's not going to hurt anything, it's just how it is.
For the OP: Try a decent wall charger. If you don't have anything better, you'll have to turn the Note OFF while charging. That should at least get your battery charged overnight. If it's a long cable, try a shorter one, that can make a difference. Or try to find a thicker cable, but that's not always a guarantee the wires inside are any thicker.
